  The output is the following
  

  To get a displayed item to render in HTML, in the definition section Security value escape special characters notitem.

  For a column of the report, ensure that the column attribute text to display as report is report Standard column rather than the default display text (escape special characters).

  However in the APEX 4.x, using an element in the Image display and support declarative BLOB is preferable to these manual methods. Images can be formatted using the HTML attributes of the element form of property, or via CSS element.

• Using the function PLSQL return Record Type Index of Tables in ADF

  I have a PLSQL function, a return type. My ultimate goal is to take this binary integer index Table and print it on the screen...

  CREATE OR REPLACE PACKAGE my_pkg IS
  TYPE t_col IS RECORD(
  i NUMBER,
  n VARCHAR2(30));
  TYPE t_nested_table IS TABLE OF t_col;
    FUNCTION return_table RETURN t_nested_table ;
END my_pkg;

  
  

  OPTION 1:
  

  1) has anyone got best practices to accept plsql RECORDS returned by a function?

  Here is an example.

  http://adfpractice-Fedor.blogspot.SG/2013/01/working-with-PLSQL-procedures-in-ADF-BC.html

  But it will be a lot of work... first of all accept the results in a loop... then store in a temporary storage can be a few VO or global temporary table and then display them on the page

  
  

  OPTION 2:

  Using the functions PIPLELINED and use in the select statement.  While I can use this select statement in the SQL query to create VO... and drag and drop the VO...

  CREATE OR REPLACE PACKAGE my_pkg IS
  TYPE t_col IS RECORD(
  i NUMBER,
  n VARCHAR2(30));
  TYPE t_nested_table IS TABLE OF t_col;
    FUNCTION return_table RETURN t_nested_table PIPELINED;
END my_pkg;

  
  

  select * from table(my_pkg.return_table);

  
  

  Wow... I'm so smart! .. really possible?  who is the best/possible/recommended option?

  I'm sure that will be the question most read by many who wants to use PLSQL instead of JAVA to the treatment and CHOSEN to use only to display the output of the PLSQL functions or procedures.

  
  

  Thank you

  Do you mean the scope of the defined Type pkg will be finished?

  I created guy outside the pkg as 'Create Type' if it works in this case?

  Yes, level objects schema (created with "create or replace type...") can be used in java and this can work.

  I think that then the scope of this TYPE will remain until the user session passes.

  Object definitions is not worn, but have their bodies.

  So, if you instantiate the data level object type schema in a plsql function, scope of this object is this function.

  Of course, if you instantiate the object as a variable package, then life of this object is equal to the lifetime of the package (which usually equals life of session db).

• How to use the functions of SetValue executeScript activity.

  Hello

  Could someone let me know how to use the function activity setValue (serialize concate, count etc) in activity executeScript. What all liberaries I need to import to executeScript. I want to perform the same task in executeScript performed in the setValue activity.

  Concerning

  Sunil Gupta

  Forgive me if I seem obtuse, but why would you use XPath functions (is that serialize, concat, and count) when there are perfectly good Java alternatives that will be much easier to use.  Java is, after all, the language used in the executeScript.  Serialize is just toString(), CONCATENATE is just + or. concat() (I assume that you are running on Java 6 web application server).  The count function is just the length() or size() methods or to the tables, the length property.  If you really need to reorganize in a variable of the XML data using a XSL stylesheet - you have access to all the functions in XPath 1.0 and XPath 1.0 power and you do not need to tinker with the headache of trying to debug Java in an environment (Workbench), which does not give you the tools that you would normally , as a contextual Editor.

• Create the view and by using the function that returns a type oracle

  How to recover someInfo.CHARGE, someInfo.some_date, someInfo.some_val? I can put them as columns in the view?

• Using the functionality of Panorama on the DSC - H55

  What is the best technique to use the functionality of panorama Cybershot DSC - H55, press and hold down the button while slowly following the arrow or press and release the button? Move from L to R very slowly or quickly?

  HI, you have limited play with the speed as you move the camera a little to get used to the speed. I know it sounds strange, but it takes a little getting used to for you to know how fast to move it to. If you move too slow or too fast, you will not receive either the scene or the camera will tell you to slow down. If you can't move the camera through any matter within the time limit, a grey zone occurs in the composite image. In this case, go faster the camera to record a complete panoramic image.

  To take the panorama photo, you can press the button all the way down and release, then move the camera in the direction of the arrow. The camera records for about 7 seconds.
